Description

TECHNICAL FIELD The present invention relates to an asbestos treatment device for stripping and collecting an asbestos layer attached as a refractory layer.

"Prior art" Due to its excellent fire resistance, it became clear that the asbestos that had been applied to various places as a fireproof layer in a building would cause pollution, and its scattering over time became a problem, and stripping and recovery is being promoted. .

Most of the methods use a large vacuum cleaner to suck and collect the dust that has been stripped and deposited on the floor. In this case, an operator who strips off asbestos and an operator who suctions and collects accumulated dust with a vacuum cleaner have a high risk of inhaling dust and must wear protective clothing that does not move freely. Also, in order to prevent the stripped asbestos from becoming dust and scattering in the vicinity, the room with the stripped asbestos layer must be sealed. Moreover,
Great care must be taken not to scatter asbestos dust collected and bagged during transportation.

"Problems to be solved by the invention" With the conventional means, there is a problem that the operator, the stripping treatment space, and the great restrictions on transportation are added as described above, and the stripping and recovery of asbestos cannot be performed quickly and easily. there were.

The present invention provides an asbestos treatment apparatus that can be put in a solidified state without the worker having to forcibly wear clothes or wear it, without the need to separately seal the stripping treatment space, and in the transportation without fear of dust scattering. It is intended to be provided.

"Means for Solving the Problems" In order to achieve the above object, in the asbestos treatment apparatus of the present invention, a dust water-soluble treatment in which a filter is laid under a watering shower and a spray chamber is formed under the filter. Part and the one side of the peripheral wall connected to the spray chamber via a flexible hose are cut off for inserting a rod and a hopper provided with a crusher at the base and the reservoir part of the spray chamber are communicated with dust. It is composed of a dust filter for receiving the melted water and an intake portion for forcibly exhausting the air in the water spray shower portion through the air cleaning filter.

[Operation] In the asbestos treatment device configured as described above, the hopper with a cutout on one side under the intake condition of the intake section is reliably peeled off at the corner where the stripping rod is easy to operate. The asbestos that is taken and falls is received without scattering, crushed by a crusher and sent to the spray chamber. Therefore,
The stripping operator does not need to attach the protective film, and the stripping processing space need not be sealed.

Part of the air containing the crushed dust of asbestos falls under the spray of water and falls into the pool, and part of the air crosses the water under the sprinkler shower and falls with the water as it becomes water-soluble and water-soluble.

The air in which the asbestos dust contained as described above is solubilized is exhausted through the air cleaning filter. On the other hand, the accumulated water in which the asbestos dust is dissolved is sent to a dust filter, dehydrated and compacted in a state where there is no risk of scattering of the water content, and packed and transported.

Therefore, there is no risk of scattering during transportation.

[Examples] Examples will be described with reference to the drawings. Fig. 1 is a flow chart of the device of the present invention, Fig. 2 is an overall bird's-eye view of the device, and Figs. , Plan view, Fig. 4a
5a to 5c are front and side views of the hopper, FIG. 5a to 5c are front and side views of the dust filter mounting table, and 6a to 6c are front and side views of the forced exhaust unit. .

In the figure, in the dust water treatment unit 1, a filter 3 is laid under the water spray shower 2 on the ceiling surface, and the filter 3 promotes the intersection of air and water. Below the filter 3 is the spray chamber 4,
A spray nozzle 5 is provided at the upper end.

On the other hand, the hopper 6 intentionally opens one side of the peripheral wall with a notch 6a for insertion of a stripping rod, but the asbestos dust stripped from this part is scattered to the surroundings by an intake device described later. It does not arise from being connected.

Therefore, the worker only has to drop the stripped asbestos into the hopper 6, and at this time, the notch 6a is convenient. A crusher 6b is provided at the base of the hopper 6, and the stripped asbestos is immediately crushed. This crushing is for not only facilitating the transportation of asbestos by the flexible hose described later but also for facilitating the dissolution in water.

In many cases, the hopper 6 is actually pressed against the ceiling surface, and it is good to be instructed by the movable lifter 7 or the like as shown in FIG. The hopper 6 is connected to the guide port 4a of the spray chamber 4 via a flexible hose 8. The air containing the pulverized asbestos introduced into the spray chamber 4 contains water in the spray from the spray nozzle 5 and falls. Those that do not fall are water soluble in the filter 3 and fall with the water.

The above-mentioned airflow is generated when the shower 2 is connected to an intake section 11 forcibly exhausted by a fan 10 or the like via an air cleaning filter 9. The accumulated water 12 in the lower part of the spray chamber 4 in which asbestos dust is dissolved is discharged to the outside and dust filter 13
Sent to. If the dust filter 13 that receives the accumulated water 12 is arranged as a separate body under the drain pipe from the device body as shown in the example in the figure, when replacing the dust filter 13 when it is full, a temporary operation This is preferable because the work can be performed without stopping.

If the asbestos dust is dehydrated and compacted in the dust filter 13, there is no risk of scattering into the air in a water-containing state, and it is solidified and easy to transport (if it is stored in a waterproof bag, scattering is surely prevented).

In the figure, 14 is a water filter which is good for reuse of water, and if the waste water from the dust filter 13 is purified and sent to the spray nozzle 5 and the sprinkler shower 2 via pumps 15 and 15 '. Good.

Incidentally, as shown in the figure, it is good that the shower 2 is provided with a promoting pipe 16 in the accumulated water 12 to promote the flow to the dust filter 13 to accelerate the treatment.

The respective parts of the device of the present invention are integrated as shown in FIG. 2 when in use, but it is advantageous to consider that the respective parts can be assembled separately by incorporating them into the field.

The positive side, the side, and the plane of each part in such a case are shown in FIGS.

"Effects of the Invention" Since the present invention is configured as described above, it has the effects described below.

(1) The stripped asbestos lumps will not be immediately received by the hopper and will not be scattered around.Therefore, operators who operate the stripping rods at a predetermined interval will not need to wear clothes. , You can freely peel off the work.

(2) Since the suction force of the hopper described above reliably prevents the asbestos from scattering to the surroundings, it is not necessary to seal the stripping treatment space.

(3) Stripping Asbestos is convenient because it is pulverized and then collected in a water-containing state, so there is no risk of scattering during post-treatment.
